ABSTRACT:
A hydraulic vent valve for use on ship cargo tanks is disclosed which is utilized to maintain a constant head of pressure or vacuum on containerized fluid and to provide leakproof isolation between the stored fluid and the atmosphere. The valve features a reservoir, a divider for dividing the reservoir into two chambers, an aperture in the divider through which liquid can flow, reservoir liquid in each of the chambers in an amount sufficient to cover the aperture when pressures inside of the chambers are equal, an intake connected to the reservoir for communicating pressures on the stored fluid to the surface of the reservoir liquid in one of the chambers and an exhaust for communicating atmospheric pressure to the surface of the liquid in the other chamber.
